Another 10 people were injured, including the driver, after the refuse truck swept along a crowded pavement in the city centre yesterday afternoon, knocking pedestrians down "like pinballs", according to one horrified eyewitness.
The Church of Scotland organised a prayer service for the victims today morning and opened a book of condolences at St George's Tron church, a short walk from the scene of the tragedy on George Square.
Floral tributes were placed at the scene of the crash, which police said appeared to have been a tragic accident. The dead included five women and one man, police said.
First Minister Nicola Sturgeon described yesterday's incident as "another sad day for Glasgow and Scotland".
"This morning it's a city with a broken heart but it will get through this as it got through the Clutha (helicopter) tragedy," she told BBC radio.
The local authority bin lorry veered over a distance of around 300 metres (about 1,000 feet), only stopping when it crashed into a hotel near Queen Street station.
An investigation was under way to establish exactly what had happened, police said.
